Using external and internal formwork in a W (double) configuration! Applicable to ISM method as well.
The "W Mer Method" is a soil cement construction method that effectively utilizes locally generated soil and sediment, employing a residual formwork system for the construction of external protective concrete (cover concrete). By vertically installing the internal formwork, it is possible to ensure proper compaction of the internal material (INSEM material) even at the ends near the formwork panels. It can also be applied to the ISM method. 【Construction Examples】 ■ Shizuoka Prefecture Fuji Civil Engineering Office, First-Class River Improvement Work on Denpozawa River ■ Chubu Regional Development Bureau Tajimi Sediment Control National Route Office, Kiso River System Naka Tsutsumi No. 2 Sediment Control Dam Construction ■ Kinki Regional Development Bureau Kinokawa Dam Integrated Management Office, Sako District Landslide Countermeasure Work ■ Kyushu Regional Development Bureau Tachino Dam Construction Office, Tachino Dam Entrance Closure Embankment and Other Works *For more details, please refer to the PDF materials or feel free to contact us.
